3m+5
Josh’s marbles can be represented by m
Matthew’s marbles can be represent by 3m+5 (the 3m is for triple what Josh has which is m)
Answer:
A
Step-by-step explanation:
In this problem, first u would have to keep the base of 3, then multiply the two powers together to get -28.
However, u can't leave a negative power in the numerator, so u bring the base and the power down into the denominator, change the sign of the power to make it positive, and put a 1 in the numerator.
Answer:
m = 1/10
Step-by-step explanation:
A’B’C’D’ is obtained by translating ABCD 3 units to the right (i.e. a positive translation of 3 units along the x axis) and 5 units down (i.e. a negative translation of 5 units along the y axis).
So, in order to go back to ABCD, we have to invert both translation: we have to go 3 units to the left (i.e. a negative translation of 3 units along the x axis) and 5 units up (i.e. a positive translation of 5 units along the y axis).
Answer:
Step-by-step explanation:
1) we know that
Sally can paint the wall in 54 minutes
so
The 100% of the wall ------> she can paint in 54 minutes
by proportion
calculate how much is the percent of the work in 36 minutes
That means
Sally in 36 minutes can paint the 66.67% of the wall
2) Sally and Ethan work together, they can paint the wall in 36 minutes
so
Ethan in 36 minutes can paint (100%-66.67%)=33.33%
by proportion
Calculate how much time does it take for Ethan to paint the wall by herself
